Tensor and Java shapes mismatch super-issue #180

Open mgalgs opened 3 years ago

mgalgs commented 3 years ago

Cannot copy from a TensorFlowLite tensor (StatefulPartitionedCall:4) with shape X to a Java object with shape Y. seems to be a common problem (#176, #166, #162, #150, #147, #140, #109, #94, #84, #46, #41, #10).

Any guidance on resolving such shape mismatches?

Some additional validation with a more instructive error message might be helpful given the number of people having this problem.
